Title: Production of organic fertilizer
Inventor: INOUE SATOSHI
IPC: C05F17/00
Filed: 1991-03-28
Abstract: PURPOSE:To achieve composting of organic wastes in a short time and obtain uniform compost free from malodor by kneading wastes containing organic materials under pressure to raise the temperature to a prescribed level by the heat of friction, releasing the pressure, finely pulverizing the mixture and recycling a part of the obtained compost. CONSTITUTION:Waste containing organic materials or a mixture of the waste and a cellulose-containing organic material is adjusted to a water-content of 46-65wt.%. The adjusted material is subjected to shearing and kneading under pressure to raise the temperature to 40-90 deg.C by the frictional heat. The low- temperature bacteria are exterminated and the material is uniformly fermented in a short time by this process. The fermented product is released from the pressurized state and finely pulverized in contact with air. The fermentation of the product is proceeded for >=5hr at >=40 deg.C and 5-60wt.% of the produced organic fertilizer is returned to the system and recycled.

Title: Sonar system
Inventor: POORU PII OODEI
IPC: G01S7/62
Filed: 1994-04-27
Abstract: PURPOSE: To identify the presence of an unknown object under water by quantizing the intensity of each pixel into one of a plurality of levels, and comparing the distribution of pixel levels on range scanning in each cross range position. CONSTITUTION: A series of sonar pulses are transmitted toward the sea bottom in a range direction 16 vertical to the moving direction of a sonar system 10 while moving the sonar system 10 forward or a cross range direction 14, and a signal indicating the reflection intensity of a two-dimensional array of pixels 20 is stored. Each pixel 20 shows reflection intensity in a position of the range direction 16 and a specified position of the cross range direction 14. The intensity of each pixel 20 is therefore quantized into one of plurality of levels, and the distribution of pixel intensity levels on range scanning in a cross range position is compared with the distribution of pixel intensity levels on range scanning in another cross range position to identify an unknown object in the water. Concentration on the identification of the object is therefore possible so as to be able to support an operator with little experience.

Title: Analog-digital converter
Inventor: SAITO SEIICHI
IPC: H03M1/14
Filed: 1985-04-26
Abstract: PURPOSE:To obtain the converter using a high-speed AD converter with low resolution and utilizing the advantage of its high speed to improve the resolution by providing a level shift circuit, a parallel conversion AD converter, a high- order converting means and a selector of each specific design. CONSTITUTION:One analog signal is separated into plural analog signals having different DC levels by plural level shift circuits 2-5. Each analog signal is subjected to AD conversion by parallel AD converters (ADC) 10-13, and high- order AD conversion data is obtained from a high-order converting means 15 by using the AD conversion data to discriminate whether the ADC is in scale-out or not. Then low-order AD conversion data is obtained by using a selector 16 to change over output lines of the ADC 10-13. Thus, the converter with high resolution, high speed, compactness and low cost is attained.

Title: Uninterruptible power supply
Inventor: NAGAI NOBUYUKI
IPC: H02J9/06
Filed: 1995-04-17
Abstract: PURPOSE: To provide an uninterruptible power supply in which a switch is connected with the other UPS side simultaneously with firing of a stand-by thyristor switch on the other UPS side upon failure of one UPS thereby interrupting the load current instantaneously when the UPS is switched and feeding the load current through the switch during normal operation of the UPS. CONSTITUTION: Upon failure of a UPS 2A, it is detected by a power supply switching control circuit in a switching board and a firing command is delivered to a thyristor switch 3B. When the thyristor switch 3B is fired, power is fed temporarily from both UPSs 2A, 2B thus realizing perfect uninterruptible power supply. On the other hand, a signal is delivered to a switch operating circuit simultaneously with provision of the firing command to the thyristor 3B and the UPS 2B is switched by a switch 6 following to firing of the thyristor switch 3B. An extinction command is also delivered from a power supply operating circuit to a thyristor switch 3A and power is fed to a load 5 only from the UPS 2B. With such constitution, a highly reliable system is realized.

IPC: F24F7/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To effectively catch the smoke of a cigarette, and besides, permit the miniaturization. SOLUTION: Smoke Sb is sucked together with air from the air suction port 11 of a lower blower 1 and is discharged upward from an air discharge port 12 through an air guide passage 13 by rotating the fan 14 provided at a lower blower 1. The air A including the smoke from the air discharge port 12 is sucked from an air suction port 21 by the rotation of a fan 28 provided at the upper blower 2, and the particles, shell, etc., within the air are sucked and discharged through a filter 27 for air cleaning.  At this time, a continuous air current A arises between the air discharge port 12 of the lower blower 1 and the air suction port 21 of the upper blower 21, so this air cleaner can intercept the flow of smoke from the front side of the body of the air cleaner to the rear side, and besides since the periphery gets in negative pressure condition by the air current A, the rising smoke can be drawn to the air suction port 21 of the upper blower 2, and it becomes possible to effectively suppress the scattering of the smoke.
